Sorry I'd like to add up one more thing here.
Having 10x7 two blade prop did not do justice rather than having 11X6 Prop. I'm not gonna use any prop on .45 or .46 Motor other than 11X6.
dont blame the prop, while that prop could have raised your stall speed slightly the 11x6 would have lagged your engine a lot more which could have hurt you even worse. i would use a 11x5, doesnt bog your engine down as much yet lowers your stall speed quite a bit (this is asumbing your engine is running and under some throttle).
